Solitrend MMP20 (Option D) SWZ probe
Hauser 27
Please note the following:
• There should not be any residue of old concrete around the ceramic on the probe surface.
Clean the surface with a wire brush if necessary.
• The amount of concrete in the bucket should be at least 3 cm higher than the length of
the probe head (<18 cm). In the case of concrete with a high water content, it is
particularly important to ensure that the concrete does not segregate during or as a
result of the measurement.
• Insert the probe head fully into the concrete at the edge of the bucket at a slight angle.
• Tap the side of the bucket to make the concrete more compact around the probe. This
ensures that the fresh concrete is optimally packed around the probe surface for the
measurement.
8.3.2 Measuring concrete with flow class F2, F3 or F4
1. Insert the probe into the fresh concrete at the edge of the bucket

2. Take an individual measurement
3. Remove the probe from the bucket
 When the probe is removed from the concrete, the fresh concrete can segregate
at this point and fine particles can enter the cavity.
4. Insert the probe into the fresh concrete again at the side of the bucket, spacing the
probe approx. 70 ° from the previous position
5. Tap the side of the bucket (e.g. with your foot) to make the concrete more compact
around the surface of the probe.

6. Take another individual measurement
7. Insert the probe again at the side of the bucket, spacing the probe approx. 70 ° from
the previous position
